Here is a way to reset but make sure you follow the instructions correctly.
turn off machine
press online and escape buttons together whilst turning on machine,
when display comes up wait till three options are listed, use arrow button down to select engine, use arrow right to select mode(5.mode) and ok, left arrow to 5.810 SC RESET. OK. PRESS OK AGAIN AND THEN EXECUTE AT BOTTOM OF SCREEN.
Turn off printer and wait ten secs then turn back on.
If only temp error this should reset and start up again, Good luck

How do i fix the error message set pcu correctly on my ricoh aficio sp c811dn


Turn the machine off. Open the access door and remove the cyan photoconductor unit. Check the contact pins are straight and undamaged. Gently reinsert the unit. Turn the power back on. If the machine still does not recognise the pcu is inserted it is probably damaged and needs replacing. How many copies/prints has your machine done?

Ricoh aficio c420dn wont print black


Hi, my experience with this machine is that the gear that drives the black pcu breaks or cracks. Usually caused by the pcu being too hard to turn. I always turn the developer gear in the pcu before installing it just to loosen the toner.

Ricoh Aficio SP C811DN Printer. after printing 9 pages it will stop and displays CS367 error code saying 'Functional problem turn power switch off then on. Can you tell me what that means and how fix...


SC367 is a toner density error having to do with yellow. If you've tried turning the machine off (with the power switch on the lower left side) and turning it back on and that doesn't help, your next move should be to replace the yellow photoconductor unit (PCU).

Thanks for using FixYa!

My Ricoh Aficio SPC811DN printer keeps asking me to replace my PCU colour all the colour carteridges are over half full what do i have to rplace


The PCU is the drum unit. There is one for each colour (C,M,Y & K). Each PCU has a 'life' and the machine will ask you to replace it when it has reached the end of its expected life. The PCU life has nothing to do with the amount of toner that you have in the cartridges and they need to be changed independantly.

Add Toner stuck on & Replace Photo Conductor Unit (PCU)


I suspect that it is the PCU causing the problem, and the message should clear once the PCU is installed and it (automatically) runs it's calibration cycle. Likely the toner auger gear has seized on the PCU, and broken. If the light does not go off after installing the PCU, then you may need a technician, as the toner motor may not be working, or there is a blockage within the toner hopper itself.....but again it is likely the PCU, especially if the toner bottle was empty when it needed replacement. Was it empty?? Did the machine work for a few days, or at least for a while? If so, it seems like too much of a coincidence that this problem would come up at this time.

Good Luck :)

13. ** Important** remove the PCU unit. Empty the toner from the PCU by sliding the shutter on the bottom of the PCU to the side and tapping the PCU.
